18:42 U.S. Robotics supports Rockwell's V.Fast Class modulation

SKOKIE, Ill., Nov. 10 /PRNewswire/ -- U.S. Robotics, Inc. (NASDAQ: USRX) today
announced it has recently signed an agreement with Rockwell International
Corporation (NYSE: ROK) to incorporate Rockwell's V.Fast Class (V.FC) technology
for high-speed data modem transmission into selected U.S. Robotics products.

"It is important to help our customers increase throughput and maintain
compatibility as the final pieces of the ITU-T V.34 standard are put in place,"
said Jonathan Zakin, U.S. Robotics executive vice president, sales and
marketing.  "Our customers rely on products that provide the widest range of
connectivity options and the highest speeds available.  Our support of non-ITU-T
technologies such as V.FC assures that our products meet these needs."

V.FC technology uses line probing techniques that permit adapting to symbol
rates which optimize the configuration of the modem to achieve the maximum
throughput supported by the telephone networks.  This technology uses the wider
bandwidth available on today's telephone networks, making it significantly more
immune to noise and other telephone line impairments than V.32 bis technology.

"U.S. Robotics has a well-recognized position in the industry as a leading modem
supplier.  We are pleased with their selection of Rockwell's V.Fast Class as an
implementation choice for pre-V.34 modem products," said Armando Geday, Rockwell
International's business director, modem systems.

Rockwell's Telecommunications Business Segment includes three principal
businesses:  the Digital Communications Division (DCD), the Switching Systems
Division (SSD) and the Microelectronics Technology Center (MTC).
DCD,headquartered in Newport Beach, Calif., has been a pioneer in modem
technology for more than 30 years.  Today it is a world leaders in fax and data
modem components.


U.S. Robotics, Inc. is a leading designer, manufacturer and marketer of data
communications systems products.  Both corporate headquarters and manufacturing
